REPEATING DEVICE FOR TALKING-MACHINES.

To all whom it may concern: I

Be it known that I, ALEXANDER FRASER, a subject of the King of-Great Britain, and resident of R'enfrew, in the Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Repeating Devices for Talking-Machines,

of which the following is a specification.

This invention relates to improvements in a repeating device for talking machines,

particularly. machines of the so called Edi son type, in which the tone horn extends below the records and swings about a pivot at its forward end, and the objects of the invention are to provide a simple and effective device by which a record may be caused Specification of Letters Patent; V Patented J an. 13, 1920.

member 11, worm gear 1.2, meshing with the worm 13 which drives the turntable (not shown). The shaft 15 connected 'to the worm 13 carries the enlarged worm 14 which known mechanism of the Edison talking. mach1ne. In the operation of the talking machine when it is desired to disengage the needle from the record and release the tone to repeat, or cause to be automatically repeated any given number of times,

Further objects of the invention are gen-- orally to improve and simplify the construction of the device and enable the various parts to better perform the functions required, of them. The device consists essentially of the improved construction hereinafter described in detail in the accompanyin specification and drawings. nthe drawings: I Figure l is a plan portion of atalking machine embodying the present invention.

Referring to the 'drawings,'A represents about the vertical shaft 10, mounted upon a suitable cabinet B. The construction of the talking machine itself with the'method' of part of the present invention, and only such parts of the machine are shown as are necessary to'coii erate with-the operation of the parts of th1s invention. The usual-driving arm, the shaft 10 carrying the tone arm and lever 21 areadaptedto be raised by a pivoted lever 28 having a cam shaft end 24 designed to bear against thesurface of the fixed support or. cover plate 25 whereby 1 when the lever 23 is pressed downwardly the shaft will'be raised. I prefer; in my lnvention to augment the lever by means of a spiral. spring 26 surrounding the shaft 10 at the bottom bearing against the lower connecting bracket 27 which is connected to the tone arm and comprises the shaft.

In regard to the present invention the adjustable tappet member 30 is provided,

carried by the swinging lever 21 and to has adjustable support. I have shown the lever with its upper end adjustably mounted on pin '31 held between brackets 32 and 33 provide for different sized records this lever memberis indicated by means of a pointer The opposlte :end

35 on' the tappet member extending over a scale 36 formed on the clamp 34.

It is not necessary to provide any means to hold the tappet in posit on for the reason that the lower end which carries a conveniently placed button 36, covered by 10.0.; material such as rubber, is sufiiciently below i the pin 31 to cause a turning moment to be i produced whichwill prevent sliding.

Mounted on the shaft 18 is a crank 40,

having a projecting pin 41 adapted to enis centrally pivoted to the lower end of'rod 43, the upper end .of which rod is clamped to the fixed plate25.

of the lever 42 to that engaged by the pin 41 isprovided with a gage the free end of a lever 42, which-lever perforation'thmugh which the rod 44 extends; the inner end of the rod being conwhile the outer end is screw threaded having a nut 46'thereon, which engages the surface of the lever, the lever being held in outermost position on the rod by means of a spiral spring 47 which extends from the clamp 45 to the lever.

The position of the free end of the lever is normally, slightly in advance of the pin 41 to .the right as shown in Fig. 1, so that the pin may rotate and clear the lever. When the lever 21 swings over, the button 36 on the tappet 30 will engage one end of the lever 42 and push. it sidewise to the left as shown in Fig. 5 into the path of the I pin 41 thereby permitting the pin as it 1 lever 63 of the usual stopping mechanism of the phonograph, the disk 60 is mounted on turns with shaft 18 to engage and depress the end of the lever moving the opposite end upwardly. The upward movement of the lever 42 will be transmitted to the rod 47, clamp 45 and the shaft 10, and this shaft 10 will carry the tone arm A, upwardlylifting it until clear of the disk and when this takes place the tone arm will swing to its original position, under the action of the tension spring 50 which is provided for that purpose extending between the bracket 51 on tone horn and eyelet 52 on the cabinet B. The tone arm will 'reach its original position at the same time the rotation of the pin 41 causes the lever 42 to be moved. on its pivot to return the tone arm to its normal. pos1t1onand the lever under pressure from the spring 47 will turn about the axis of the pin 43 and resume its normal position; in this way the reproducer will be next lowered gently onto the-record or disk.

Mechanism may be provided to cause the repeating action to be terminated after a given number of repetitions of the record. The mechanism which I have devised comprises a disk 60 carrying the ratchet 61 and a tappet arm 62 which in a given position is adapted to engage and actuate the operating a plate 64 which may conveniently be formed with a slot 65 to enable it to be inserted in position above the plate 25 on the rod with the shaft 10 extending through the slot 65. The ratchet 61 is designed to be engaged by th spring pawl 66- carried by a lever 67 .pivotailly mounted on the pivot pin 68 which pivot pin connects the disk 60 with the plate 64,'the lever 67 being operated from the lever 42. through the medium of 'acon.

. necting rod 68 extending from the end of the lever 42 and through the lever 67. It

will he therefore seen that each 0 eration of the lever 42 will move thero swing the lever 67 and turn the ratchet 61 the distance of one tooth. When the lever 67 has been turned sufliciently to brlng the lever 62 into engagement with the lever 63 the automatic stopper will be thrown into operwhich may be applied to any existing talk mg machine of the same construction and method of operation.

'AS many changes could be made in the .above construction, and many apparently widely different embodiments of my invention within the scope of the claims, constructed withoutdeparting from the spirit or scope there, it is intended that all matter contained in the above specification and accompanying drawings, shall be interpreted as illustrativeand not in a limiting sense. What I claim asmy invention is:
